C++20 Full Throttle (part 1)

Code repository for my C++20 Full Throttle (Part 1) live training.

The title of this live training is now:
Modern C++ Full Throttle: Intro to C++20 & the Standard Library — A Presentation-Only Intro to Fundamentals, Arrays, Vectors, Pointers, OOP, Ranges, Views, Functional Programming; Brief Intro to Concepts, Modules & Coroutines, and several C++23 enhancements.

This is a one-day, presentation-only, code-intensive intro to C++20 core language and library fundamentals with introductions to various C++20 features including Ranges/Views, Concept, Modules and Coroutines, and various C++23 features. The "Big Four" C++20 features are covered in-depth in C++ Fundamentals video course on O'Reilly Online Learning.

Running the code

To compile and run the C++ code, you’ll need one of:

• Visual C++ (I’ll use Visual Studio Community 2026),
• Any version of g++ 13 or higher (15 is current)
• Any version of clang++ 16 or higher (21 is current).

Visual Studio Community download

g++ or clang++

To quickly get up and running with g++ or clang++, I recommend Docker:

• Install Docker Desktop: https://www.docker.com/products/docker-desktop/
• docker pull gcc:latest
  • (you can also do a specific version like gcc:15)
• docker pull teeks99/clang-ubuntu:21

My Before You Begin and Lesson 1 videos in C++ Fundamentals video course on O'Reilly Online Learning discuss installation and compiling details.

Running Docker Containers for g++ & clang++ and Compilation Commands for Both

Running the gcc:latest Docker Container from the Command Line

• Change to the folder containing the course examples then…
  • docker run --rm -it -v .:/usr/src gcc:latest
• Compiling/running
  • g++ -std=c++20 filesToCompile -o executableName
  • ./executableName
• For examples requiring libraries in the libraries folder
  • Add -I flag followed by the include folder location

Running the teeks99/clang-ubuntu Docker Container from the Command Line

• Change to the folder containing the course examples then
  • docker run --rm -it -v .:/usr/src teeks99/clang-ubuntu:21
• Compiling/running using the g++ standard library (clang++ defaults to this)
  • clang++ -std=c++20 filesToCompile -o executableName
  • ./executableName
• Compiling/running using the clang++ standard library
  • clang++ -std=c++20 -stdlib=libc++ filesToCompile -o executableName
  • ./executableName
• For clang++ 16, also compile with: -fexperimental-library
• For examples requiring libraries in the libraries folder
  • Add -I flag followed by the include folder location
